UFCThe Ultimate Fighting Championship (UFC) is a U.S.-based mixed martial arts organization, recognized as the largest MMA promotion in the world. The UFC is headquartered in Las Vegas, Nevada and is owned and operated by Zuffa, LLC. This promotion is responsible for solidifying the sport's postion in the history-books.
UFC is currently undergoing a remarkable surge in popularity, along with greater mainstream media coverage. UFC programming can now be seen on FOX, FX, and FUEL TV in the United States, as well as in 35 other countries worldwide.

Georges St-Pierre was not 100 percent when he fought -- and eventually beat -- Nick Diaz at UFC 158 last weekend.

According to St-Pierre's trainer Firas Zahabi, the UFC welterweight champion suffered an achilles injury before the March 16 fight, and the injury may have worsened during the five-round bout.

"I was worried it would tear during the fight," Zahabi told MMAFighting.com. "We had to cut his last sparring [session] short due to his injury. He had a week to rest it and then the fight."

The news was first reported by Le Journal de Montreal.

Zahabi said he believed the achilles injury was on the same right leg St-Pierre had surgery on last year to repair a torn ACL, but he didn't think the two injuries were related. He added that he has yet to speak to St-Pierre about the ailment and has no idea how long he'll be sidelined for.

However, the Tristar Gym head coach wants St-Pierre take some time off, considering the injury and that the Diaz fight was his second in four months. In fact, Zahabi doesn't want him to return to action for at least six months, if not more.

"He's 32 soon," he said. "He needs to respect that."

St-Pierre's manager Rodolphe Beaulieu echoed Zahabi's sentiments, while confirming that St-Pierre returned to training on Wednesday.

"He wants to take a couple of months off because his two fights were very close to each other," he said, "and he wants to enjoy the summer. We haven't talked to the UFC yet, so we don't what their plans are for Georges yet.

Up next for St-Pierre is Johny Hendricks, who told FUEL TV's "UFC Tonight" on Tuesday that he was hoping the welterweight title fight would take place in August, so he could fight at least one more time in 2013.

UFC welterweight champion Georges St-Pierre was battling the effects of a fever, according to his trainer Firas Zahabi. GSP defeated Nick Diaz via decision over the weekend at UFC 158: St-Pierre Vs. Diaz.
Zahabi, during a recent appearance on The MMA Hour, disclosed that St-Pierre was "a bit warm," but the thought to pull out of the fight was never mentioned.

"Everybody is a little injured, everybody is a bit busted up," Zahabi said. "He wasn't sick enough to pull the plug on the fight, but he did have the start of the fever. He was warm and he was feeling a little uneasy. He was feeling a little sick."

GSP mentioned taking some extra time off following the victory, saying he has been going full-force since knee surgery. Johny Hendricks is expected to be his next foe whenever he returns to action.

The fever/sickness might explain why GSP gassed for the first time in a decade. I remember thinking as the fight progressed that St. Pierre looked a little 'off'.
